The object of the present invention is to provide novel, simple and effective means for securing roofing material, such as insulation, to a metallic or other deck structure.

An embodiment of the invention that is at present considered the preferable one is illustrated in the accompanying drawings,

wherein:

Figure 1 is a perspective'view of a portion of a metallic roof deck showing the fastenin means in place.

igure 2 is a sectional view with a layer of insulation upon the deck and such insulation being secured by the novel means.

Figure 3 is a view in face elevation of one of the fasteners.

Figure 4 is an edge view of the same.

Figure 5 is a detail sectional view on the line 5-5 of Figure 3.

In modern deck structures, there are employed channel members of sheet metal that are intertitted side by side to produce the foundation or deck. As shown each of these members consists of a top wall 6 and side walls 7. One of these side walls is 'provided with a reversel turned flange 8 forming a groove, while the opposite wall is provided with an outstanding flange 9. When these members are assembled into a deck, the yside walls 7 are located alongside each other and the fiange 9 of one member engages in the groove formed by the reversely formed flange of the adjacent member. The members are thus effectively interlocked. Upon this deck structurehis usually placed a layer of heat insulation 10 and it is the object of the present invention to provide novel means for securing this insulation or other overlying roofin materialin place.

For this purpose fasteners are employed that are preferably formed of sheet` metal. Each fastener consists of a rectangular body plate 11, the length of which is ma e substantially the width of the side walls 7.- Projecting from one of the end edges of this -body plate 11 is a pair of relatively short 'spurs 12 that are located ad'acent to one corner of the plate. Extending rom the opposite end edge of the plate is a longer spur 13 that is located at the diagonally opposite corner to the spurs 12. 'This spur 13 is pointed and preferably is provided with a longitudinal ribl/l that stiens the same, said rib however, preferably terminating short of the lpoint so that the end can be readily bent.

Because of the relation of the spurs it will be evident that an extended fiat edge l5 is provided directly opposite the spurs 12.

In usi/ng these devices, they are driven into the joints between the side walls 7 at desirable intervals. When so driven by hammering upon the edge l5, the spurs 12 are caused to be ent into the groove between the flanges 8 and 9, and as a matter of fact actually bite into the metal of the anges so that the fastenere are effectively anchored in place, said spurs 12 when in place constituting offset anchoring elements. The spurs 13 are left in u standing relation and the insulation 10 or ot er fabric roofing material is then placed upon the deck and hammered down over the spurs by wooden mallets. The spurs are thus claused to pierce the material 10,. after which t e illustrated in Figure 2, and thereafter the waterproofing is laid over the insulation and the ends of the fastening devices.

This structure not only produces an effective fastening means, but obviously it is a plied by a workman on the deck and no worlman has to operate beneath the deck. One of the disadvantages of fasteners heretofore employed has been that they pass through the deck, requiring a workman beneath the same. More than that in cold weather these fasteners which project below the deck will cause a condensation of moisture. lThey therefore require special treatment. This is entirely obviated with the present structure.

From the foregoing, it isthought that the construction, operation and many advantages of the herein described invention will be apparent to those skilled inthe art without further description and it will be understood that various changes in the size, shape, proportion and minor details of construction may be resorted to without departing from the spirit or sacrificing anyfof the advantages of the invention.

free ends are bent over or clinched as What I claim, is: 1. A roof structure comprising a deck formed of deck members having top walls, meeting side Walls and interfitted flanges at the bases of said side walls, roofing material lying on vthe deck, and fasteners for the roofing material located between the meeting side walls of the deck members and having offset anchoring elements interposed between the anges.

2. A roof structure comprising a deck formed of deck members having top walls, meeting side walls and interfitted flanges at the bases of said side walls, roofing material lying on the deck, and fasteners for the roofing material comprising body plates located between the meeting sidewalls of the deck members and having offset anchoring spurs interposed between the flanges.

A roof structure comprising a deck formed of deck members having top walls, meeting side walls, and interfitted flanges at the bases of said side Walls, roofing material lying on the deck, and fasteners for the roofing material comprising body plates located between the Imeeting side walls of the deck members, said plates having upstanding spurs engaging the overlying roofing material and having at their lower ends, offset spurs interposed between the interfitted flanges.

4. A fastener of the character set forth comprising a body plate for insertion in .the

joint of a roof or like structure, said plate raving bendablespursprojecting from its opposite end edges, and disposed out of alignment to permit one portion of one edge to be utilized for hammerin1P upon, and the spur projecting from the other edge being in line with such portion.

5. A fastener of the. character set forth comprising a body plate for insertiony in the 'oint of a roof or like structure, said plate aving a tapered spur-,projecting from one edge and having a longitudinally disposed Y rib that extends to one ofthe side edges of the spur to stiilen the same, leaving the free pointed end substantially fiat to be bent.

6. A fastener of the character set forth comprising a plate for insertion in the joint of a deck structure or the like, said plate having short bendable spurs projectinr from one end edge adjacentl one corner thereof, and a longer roofing piercing spur rojectino from the opposite end edge of t e body adjacent the diagonally o posite corner to the first spurs, t e end e ge alongside the longer spur and opposite the first spur constituting a part to be hammered on to drive the shorter spurs.

In testimony whereof, I aix my signature.
